Aqueous and acetone extracts from 15 fruits have been screened for antioxidant activity using DPPH method and ß-carotene/linoleic acid model. All fruits studied showed antioxidant activity, but in different extent. Acerola, cashew-apple, papaya "formosa", papaya "solo", orange and guava showed the higher antioxidant activity (>;70%) in DPPH method, followed by pineapple, bergamont, mango "rosa", melon "reticulares", melon "inodorus", melon "orange flesh" and sugar-apple aqueous extract (moderate, 60-70%) and mango "espada" and watermelon aqueous extract, the lowest activity. Acerola, cashew-apple, sugar-apple and guava acetone extracts exhibited higher scavenging activity toward DPPH radicals (>;70%).β-carotene/linoleic acid model index of sugar-apple aqueous extract and guava acetone extract demonstrated moderate antioxidant activity (60-70%), meanwhile acerola aqueous extract and papaya "formosa" acetone extract the lower. According to antioxidant activity, fruits can be indicated as natural antioxidants sources, pointing out acerola, cashew-apple, papaya "solo", papaya "formosa", guava, orange and sugar-apple as the highest in antioxidant capacity.Downloads
